Patent number: 11813417Abstract: In some examples, a catheter flaring device includes a housing and a pin. The housing includes an interior surface defining a cavity configured to receive at least a portion of a catheter having an entry port and engage an exterior surface of the catheter proximate the entry port. The pin is configured to be advanced into the entry port of the catheter to increase a cross-sectional dimension of the entry port. Flaring the entry port may help reduce catching of a medical device on the entry port of the catheter during a medical procedure.Type: GrantFiled: August 13, 2019Date of Patent: November 14, 2023Assignee: Medtronic Vascular, Inc.Inventors: Francis Denis McEvoy, Colm Connolly

Patent number: 10413709Abstract: A dilatation catheter includes a high-pressure balloon component comprising an inner balloon and an outer balloon. An interior of the inner balloon is in fluid communication with a lumen of the catheter for receiving inflation fluid therefrom. The outer balloon defines a separate interior within which the inner balloon is disposed. The outer balloon has a hole in a wall thereof for venting the interior of the outer balloon to ambient environment. Proximal necks of the inner and outer balloons are bonded to an outer shaft of the catheter and distal necks of the inner and outer balloons are bonded to an inner shaft of the catheter. In accordance with embodiments hereof, the interior of the outer balloon is not in fluid communication with the interior of the inner balloon, the lumen of the catheter or any other source of fluid from the catheter.Type: GrantFiled: July 14, 2016Date of Patent: September 17, 2019Assignee: MEDTRONIC VASCULAR, INC.Inventors: Aram Jamous, Colm Connolly, Colin Meade, Niall Plunkett

Patent number: 9877660Abstract: Embodiments hereof relate to methods and systems for determining a pressure gradient across a lesion of a vessel without requiring the use of a pharmacological hyperemic agent. A measurement system includes at least an injection catheter and a pressure-sensing instrument or guidewire slidingly disposed through the catheter, the pressure-sensing guidewire including at least one pressure sensor configured to obtain a pressure measurement for use in determining the pressure gradient across the lesion. The catheter is configured to deliver or inject a non-pharmacological fluid, such as saline or blood, across the lesion in order to increase a flow rate there-through, thereby simulating hyperemia without the use of a pharmacological hyperemic agent. Once an increased flow rate that simulates hyperemia is achieved, the pressure sensor of the pressure-sensing guidewire may be utilized to measure the pressure gradient across the lesion in order to assess the severity of the lesion.Type: GrantFiled: November 14, 2013Date of Patent: January 30, 2018Assignee: Medtronic Vascular GalwayInventors: Barry O'Connell, Colm Connolly, H.
